WebApproximations by Lipschitz Functions 35 a) there exists F0 a (x) for all a ∈ X b) the mapping (DF) x: X → Y, given by (DF) x(a) = F0 a (x), is linear. The mapping (DF) x is said to be the differential of F at the point x. Since Rn, endowed with the usual norm, is a Gelfand-Fr´echet space, The- orem 4.50 from [5] gives us the following result: … WebTheorem 1.11 (McShane). If f: A!R is an L-Lipschitz function de ned on a subset AˆX of a metric space, then there is an L-Lipschitz function f~ : X !R such that f~j A= f. In other words a Lipschitz function de ned on a subset of a metric space can be extended to a Lipschitz function de ned on the whole space with the same Lipschitz constant ...

WebClearly, the right-hand side of (1.1) makes sense for arbitrary Lipschitz functions f . In this connection Krein asked the question of whether it is true that for an arbitrary Lipschitz function f , the operator f (A) − f (B) is in S 1 and trace formula (1.1) holds. It … WebA function f from SˆRn into Rm is Lipschitz continuous at x2Sif there is a constant Csuch that kf(y) f(x)k Cky xk (1) for all y2Ssu ciently near x. Note that Lipschitz continuity at a point depends only on the behavior of the function near that point. For fto be Lipschitz continuous at x, an inequality (1) must hold for all ysu ciently near x ... longstock fishing
